When a solid dissolves in water, heat may be evolved or absorbed. the heat of dissolution (dissolving) can be determined using a coffee cup calorimeter. in the laboratory a general chemistry student finds that when 1.44 g of cuso4(s) are dissolved in 106.40 g of water, the temperature of the solution increases from 24.05 to 25.58 °c. the heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.60 j/°c. based on the student's observation, calculate the enthalpy of dissolution of cuso4(s) in kj/mol. assume the specific heat of the solution is equal to the specific heat of water.
